The BTK serial killer says he planned to kill an 11th victim in 2004, hanging her upside down in her north Wichita home. It’s a story police heard from Dennis Rader himself in 2005, and decided until now to suppress.

Kerri Rawson, the daughter of the BTK serial killer who terrorized Wichita over 31 years, says her father made up some of the stories he tells in a new book that attempts to explain why serial killers kill.

Editor's note:This article contains graphic and disturbing material. Dennis Rader's description of his crimes — in letters to police that have just been released to reporters — was far uglier than the emotionless account he gave in court last month.

It has been one year since the cops caught the BTK monster and put an end to his deeds. So many words have been written and so many stories have been told that many of us are tired of hearing how the monster hunted people and hurt children and dressed in women's underwear. But one story has not yet been told. And it mentions the monster hardly at all.
